Plumbing and HVAC software for time tracking and job documentation

Your service technicians are often out at customers several times a day – from a service call in the morning to an emergency call in the evening. With clockin you log every visit straight to the right job, document photos and checklists on site and keep everything in view even offline in the boiler room.

FAQ

Frequently asked questions

Does clockin meet the requirements of the new obligation to record working hours?

Yes. With clockin, working hours are recorded in line with the ECJ ruling and the German Federal Labor Court decision of September 2022. At the same time, employee self-service in clockin gives employees transparent access to their working hours.

How do I convince employees who are not tech-savvy to use clockin?

clockin was deliberately developed and tested together with tradespeople and other practitioners who do not use a smartphone in their day-to-day work. Because the app needs no training and is intuitive to operate, it causes no problems even for employees who are not tech-savvy.

Does every one of my employees need a smartphone for time tracking?

No. With the crew function one device per team is enough. The person in charge can record the hours for the whole team with it.

How does the customer confirm that a job is complete?

Your employees collect the signature right on site in the app – the confirmation is saved automatically in the matching job and can be emailed to the customer if you want.

Our service technicians often do several jobs a day – how does time tracking work then?

With clockin you record every job separately – for example a service call in the morning, maintenance at midday and an emergency call in the afternoon. Everything is assigned automatically to the matching job.

We often work in basements or mechanical rooms with no signal – is that a problem?

No. clockin also works offline. Your employees record hours, photos and checklists – the data syncs automatically as soon as there is reception again.

How do I distinguish between service, maintenance and new installation in time tracking?

Your employees select the matching activity or project when recording their hours. That gives you a precise breakdown – for later billing too.

Can clockin do more than time tracking for my plumbing and HVAC business?

Yes. Besides time tracking, clockin documents whole jobs: photos, checklists and signatures land automatically in the digital project file. On top of that come shift planning, customer management and invoicing – all in one app for your plumbing and HVAC business.
